The lyophilization process for a protein-dependent drug may very well be optimized to preserve its tertiary structure, While for a little molecule, the main focus might be extra on stopping crystallization.
Enhanced warmth transfer solutions, coupled with Innovative shelf designs and improved fluid dynamics, make certain a more uniform and successful drying process.
A number of sterilization strategies could be used, together with steam sterilization, chemical sterilization, and dry warmth sterilization. The preferred system mostly will depend on the character in the solution as well as machines made use of.
To obtain by far the most economical heat transfer concerning the shelf, tray click here and samples, tissues is usually put right about the tray devoid of plastic tubes. For much easier cleaning and sample labeling, aluminum foil can be employed to go over the tray.
